    Abstract: A method of producing a polarizing glass article that exhibits a broad band of high contrast polarizing properties in the infrared region of the radiation spectrum. The polarizing glass is phase-separated or exhibits photochromic properties based on silver, copper, or copper-cadmium halide crystals or a combination thereof, which are precipitated in the glass and having a size in the range of 200-5000 null. The glass has a surface layer containing elongated silver, copper, or copper cadmium metal particles, or a mixture thereof. The method comprises subjecting the glass article to a time-temperature cycle in which the temperature is at least about 76null C. or greater above the glass softening point, in a step to thermally form and precipitate large halide crystals, and elongated metallic particles under a stress of not over about 3000 psi, preferably not over about 2675 psi.

    Abstract: Disclosed is a method of preparing refractive microlenses in a single step, utilizing laser-induced surface structure formation in semiconductor doped glasses (SDGs). The SDG materials, in conjunction with above-bandgap wavelength laser sources, are used to fabricate lenses that operate with light of below-bandgap wavelengths. In accordance with the teaching of this invention lenses on an approximately 5-500 .mu.m diameter scale are fabricated individually or in arrays by laser irradiation of absorbing glasses. The microlenses have controllable characteristics and can be fabricated to have focal lengths as short as tens of microns. The lenses are generally parabolic or spherical in shape and are highly reproducible.
